The present invention relates to a normal incidence ellipsometer and a method for measuring the optical properties of a sample by using same. The purpose of the present invention is to provide: a normal incidence ellipsometer in which a wavelength-dependent compensator is replaced with a wavelength-independent linear polarizer such that equipment calibration procedures are simplified while a measurement wavelength range expansion can be easily implemented; and a method for measuring the optical properties of a sample by using same.

An improved sample conveyer for articulating a sample across the flat platen of a spectrum analyzer relative to a scan window in the platen. The conveyor includes a sample truck configured for movement across the surface of the platen, the sample truck having a scan aperture. A spur gear is rotatably mounted about the aperture, and a drive gear is engaged to the spur gear. The drive gear has a plurality of magnets embedded therein, and a second plurality of magnets is affixed to the sample truck. A translation mechanism resides beneath the platen which includes a sled mounted on parallel rails for linear translation there along, and a motor mounted on the sled. Magnets on both the sled and drive gear index and engage corresponding magnets on the sample truck to implement complex orbital, hypotrochoid or epitrochoid scan patterns for more accurate particulate analysis.

A biochemical substance analysis system (5) is used to detect biological characteristics of a sample in a flow cell (38), and includes a detection system (51), a scheduling system (53), a biochemical reaction system (55). and a control system (57). The scheduling system (53) is used to schedule the flow cell (38) at different sites, including sites in the detection system (51) and sites in the biochemical reaction system (55). The biochemical reaction system (55) is used to allow the sample to react in the flow cell (38). The detection system (51) is used to detect a signal from the reacted sample to obtain a signal representing the biological characteristics of the sample. The control system (57) is used to control the detection system (51), the scheduling system (53), and the biochemical reaction system (55) to cooperate. The disclosure improves automation degree and flux of the biochemical substance analysis.

The present disclosure provides an analyzer with a reduced adverse effect to photometry accompanying acceleration or deceleration of a cuvette table. An actuator drives a cuvette table where a plurality of cuvettes are disposed annularly so that the cuvette table performs intermittent rotation in which a resting state and a rotating state are repeatedly alternated, and each time the cuvette table rotates intermittently, a row of the plurality of cuvettes is displaced in the annular direction by a given number of cuvettes. In the resting state, a pretreatment part performs pretreatment to a cuvette that stands still at a pretreatment position, and a post treatment part performs post treatment to a cuvette that stands still at a post treatment position. In the rotating state, a photometry part performs photometry to a cuvette that passes through a photometric position. A controller, in the rotating state until the cuvette that stood still at the pretreatment position stands still at the post treatment position after the completion of the pretreatment, controls the actuator so that the cuvette passes through the photometric position at a fixed rotational speed, each time the cuvette passes through the photometric position.

An adapter is useful with a sample holder of a microscope. The adapter has at least one support region for reproducibly orienting the adapter in a mounted state in a sample holder support. The adapter also has a first coupling point for detachable connection to a coupling structure of a sample holder on one side, and a second coupling point for detachable connection to a coupling structure of a sample manipulator on a side of the adapter opposite to the first coupling point. The adapter is useful with the sample holder, a sample chamber, a microscope and a method for arranging a sample in a detection beam path of a microscope.
